Fight!

Popularity

Both @harlem/core and valtio are relatively new libraries and may not have the same level of popularity as more established state management solutions like Redux or MobX. However, valtio has gained some attention and popularity in the React community for its simplicity and performance.

Size

In terms of size, @harlem/core is a lightweight state management library with a small footprint. Valtio is also lightweight and designed to be minimalistic, making it a good choice for small to medium-sized projects.

Functionality

@harlem/core and valtio both provide state management solutions for React applications. @harlem/core follows a store-based approach and offers features like actions, mutations, and getters. Valtio, on the other hand, provides a proxy-based approach and allows you to directly mutate the state object. It also supports reactivity and automatic batching of state updates.

Developer Experience

Both libraries aim to provide a simple and intuitive developer experience. @harlem/core has a familiar API inspired by Vuex, making it easier for developers familiar with Vuex to get started. Valtio takes advantage of JavaScript Proxies to provide a seamless and reactive state management experience. It also integrates well with React's functional components and hooks.

Performance

Valtio is known for its excellent performance due to its efficient reactivity system and automatic batching of state updates. @harlem/core also performs well, but it may not have the same level of optimization as valtio. Both libraries are designed to minimize unnecessary re-renders and provide efficient state updates.

Community and Documentation

Both @harlem/core and valtio have active communities and offer documentation to help developers get started. However, valtio has gained more traction and has a larger community, which means there may be more resources and community support available.
